Remove device reset during application start, the reset for application

Reset in open removed because of following comments:
1- Device reset not completed when VF driver loaded, which cause VF PMD

Adding delay can solve the issue but will increase driver load time.
2- Reset will be issues all devices unconditionally, not very efficient

This patch introduces new ethdev generic API for Traffic Metering and
Policing (MTR), which is yet another standard RX offload for Ethernet
devices.
Similar to rte_flow and rte_tm APIs, the configuration of MTR objects is
done in their own namespace (rte_mtr) within the librte_ether library.
Main features:
1. Traffic metering: determine the color for the current packet (green,
yellow, red) based on history maintained by the MTR object. Supported
algorithms: srTCM (RFC 2697), trTCM (RFC 2698 and RFC 4115).
2. Policing (per meter output color actions): re-color the packet (keep
or change the meter output color) or drop the packet.
3. Statistics
4. Capability API
Following similar approach as rte_flow and rte_tm for modularity reasons,
the ops for the new rte_mtr API are retrieved through a new eth_dev_ops
function.
Metering and policing action typically sits on top of flow classification,
which is why MTR objects are enabled through a newly introduced flow
action.
The configuration of MTR objects is done in their own namespace (rte_mtr)
within the librte_ether library. The MTR object is hooked into ethdev RX
processing path using the "meter" flow action.
